The methods of'resuscitation practised up to the present, that is to say producing an artificial vacuum and superpressure in the lungs by means of compressed oxygen, breathing by the motion of the arms and compression of the thorax (either me'chani 'cally or by hand) or by inducing and compressing the abdominal integument of the patient by means of the so-called abdominal bell, show the following drawbacks. In connection with the two methodsmentioned first the head and the upper extremities of y the patient are not accessible to injections or' other medical treatment. If the latter is necessary, for instance pulling out the tongue of the patient, the treatment of resuscitation must always be interrupted. Generally in a like manner the treatment of'resuscitation must also be stopped during vomiting. The

influence upon the circulation of the blood is very slight in connectionwith the method of causing artificial breathing by manipulating the function of the thorax by hand. Breathing by means of the abdominal bell is technically complicated and its application is expensive.

These inconveniences are overcome by the present invention; The subject matter of the invention refers to an arrangement in which the abdominal parts of a patient resting on his back, by raising of the nates and pressing the upper parts of his thighs upon the abdomen, are caused to be pressed against the diaphragm thus reducing the volume of the lungs (exhalation). During the contrary movement there occurs a relaxation of the lungs and an increase of the volume (inhalation). By causing alternatively a superpressure and vacuum in the abdominal cavity a circulation oft-he blood from and into said abdominal cavity is obtained This method of breathing will be assisted by changing the position of the person to be resuscitated, namely by changing the position of the patient fromthe horizontal to the inclined head position. This change ofposition can be effected simultaneously with the movement of the legs. But it is also possible to carry on both movementsseparately, so that during vomiting of the person to be resuscitated the breathing'function by means the position horizontally in case there should occur a disturbing rush of blood to the upper parts of the body of the patient.

An. embodiment of the arrangement according to the present invention is illustrated in'the drawing by way of example. I

Figure l is a side elevation of the apparatus. Figure 2 is a similar view showing the patient in a clifi erent position.

Figure 3 is another view, in which the patient, rests in still another positlon, and

the legs can be effected-during the fixed finclined position. It is also possible, to fix Fig. t is an end elevation of the apparatus.

Referring to the drawing the apparatus consists of a board or coucha fixed hori zontallyby the arresting devices I; and 19 At a suitable point on this couch are provided two 1evers,c,.which'if desired maybe connected to one another at their free ends. The said levers are adapted to turn'about. an axis d. Thelegs of the person to be resuscitated are attached to the levers by means of the carrying devices 6, consisting of rigid or movable straps, transverse bars or the like, secured to said levers. The couch may be fulcrumed at f about an axis vertical to the direction of the body. The couch is re- 'quired to execute a turning movement to one 'side only, namely to that where the head of the patient is resting and'in such a manner, that the upper portion ofthe patients body is inclined toward the bottom. hen in- .clining the couch the body of the personse;

the person to be resuscitated is securedwithin the levers in such a manner that the upper parts of the thighs form an angle of more than 90 degrees to his upper body. By moving the leversthe upper parts of the thighs are pressed against the abdomen. 1 At the same time the person to be resuscitated is brought from the horizontal into the inclined head position (exhalation). By returning the levers in opposite direction until they reach their initial position, the horizontal posltion of thepatient is obta ned again (1nhalation), 'Sultable spring. elements it; and

If it is necessary to fix the-couch in'an inclined p'o' siti'on, for instance, when the patient 1S VOH1 iting, this inclined position can be attained by turning the couch a about theaxis The breathing function with the aid of the legs may then be continued independently. In the same manneran independent horizontal position is possible. The'advantagcs ofthe apparatus consist 1n a thorough exchange of air by means of astrong diaphragm breath-. ing,;in a strong action upon the circulat onof the blood OWlIlgQlZO the compression of the abdominal parts, in the possible-inclined position of the upper extremities (filling of the head with blood), in renderingac'cessible the head without interrupting the operation of resuscitation (pulling out the tongue of .the patient and so on), in rendering accessible the arms forthe purpose of n ection and for observing the pulse, as well as in the lpossibility of preventing by an inclined position of the patient the vomited substances from entering the bronchial ways, without the necessity of interruptingthe operation "ofresuscitation. By forming thesaidcouch a into a stretcher,a handy and effective apparatus is obtained ,r l l 1.
